      We have a logparser step in our pipeline.

      99% of the time the step takes under 1sec. but sometimes the logparser does not exit.

      and then the whole pipeline times out.

          Jens added a comment -

          I have determined the cause of the hang.

          The problem is QuickEdit in a windows console

          Our jenkins server runs via a batch script in a console.

          If quickedit is enabled and text is selected in the console. Then the jenkins server is blocked from writing to the console.

          Jenkins can still start builds and will run as normal but apparently logparser does not handle not being able to read/write to console and will hang until enter is pressed in the console. 

          I have disabled QuickEdit and this solves my problem.

          This bug can be closed if needed.
